Specification of Letters Patent. Application filed December 13,1904. Serial No. 236.653;

Patented J une 19,1806.

.Be it knownthat I, JomvA. MATl-IES,-L citizen of the United States, residing at .San

Diego, in the county of San Diego, State of,

California, have invented certain newand .use'ful Improvements in Kerosene Vapor Stoves, of which the following is a spec1fication.

This invention relates to burners for utilizing kerosene as a fuel for cooking and heating purposes and the like, and has for its primary obj eat the provision of extremely simple, compact, and durable means for vaporizing kerosene and burning the vapor intermingled with air for generating heat either for cook ing, heating, or other purposes.

A further object of the invention is to provide a combined vaporizing and air-mixing a paratus in which the vaporizingchan1ber sfi'all be so located with relation to the air and vapor mixing chamber and with'relation to the'flame. that the mixing-chamber shall be .-in the heat =zoneof the main flame from the burner, and the vaporizing-chamber shall be heated from a portion of the same flame which is utilized for heating or cooking, the relations and positions of the vapor1zingchamber and the mixing-chamberbeingsuch that allportions of the mixing-chamber as well as all portions of the vaporizing-chamber are in heat-receiving relation to the burning flame, so, that the vapor generated by the vaporizing-chamber and passing in the air vide such generating and air-mixing apparatus in such form and'so arranged that the vaporizing-chamber while receiving sufiicient' heat-from the burning flame of the burner to generate a dry gas or vapoiyjyet the heat will not be so great as to prevent the proper mix-, ture of the air and vapor in the mixing-'chamber.

A further object of the invention is to pro vide the. vaporizing-chamber at'oneside of the'mixing chamber, so that the initial heatmg of the vaporizing-chamber by alcohol flame-or any other means can be readily attained without interfering in any manner --Wit hthe vaporizing-chamber or other part or 5 rests ofitsown weight.

parts of the burner and. the provisionin COD:

nection with such. vaporizing-chamber so lyingattheside of the mixing-chamber of a portion of the burner proper extending downward at the side of the vaporizing-chamber and in open connection with the main portion of the b'urnelgso that it is impossible for the flame which heats the vaporizing-chamber to be extinguished while the main burner is in operation, or vice versa, and, further, for the provision of a covering or hood over the vap0rizingchamber, so that in the initial heating of the, vaporizing-chamber all heat from the alcoholflame or other means can be localized upon the generator to readily heat the same and to retain the heat'from the vaporizing portion of the flame upon the vaporizing-chamber when the burner is in operation.

drawings, forming apart of the specification, and in which- Figure. 1 is a plan view of the burner embodying my invention. Fig. 2 is'a longitudicylindrical casing, within which is formed the mixing-chamber 3 This casing 2 has a closed bottom l and an open to 5. Upon the top of the casing 2' the slotte burner-to If desired, this slotted burner-top 5 may be formed integral .with the cylinder 2 .orxotherwise firmly attached thereto. The slotted burner-top5 is in a single pieceof metal having arallel longitudinal vapor-slots. 6. Formed integral with the cylindrical casing 2 and extending tube 7, having an open bottom and a closed top. I

8 re resents a mixing tube extending throu the wall of the casing 2 and opening into the chamber 3, whereby communication The invention will be more readily under-' stood by reference to the accompanying.

nal sectional viewon the line X X of Fig. 1.

Fig. 4 is a partial plan downward atone sidethereof is an air-draft against the cylindrical-wall of the casing 2, deflecting the same around the wall thereof and creating an intense commotion with the vapor and air within the mixingchamber 3, insuring the perfect admixture of the air with the vapor.

At one side of the air-tube 7 the wall of the casing 2 is provided with downwardly-projected parallel slots 10, forming a slotted burner 11, which, in effect, is a continuation of the slotted burner 5. This slotted burner 11 may, if desired, be formed as a part of the burner 5 and a portion of the wall of the easing 2 cut away to receive the same. Preferably the burner portion 11 is arched, so as to provide for greater area in the inlet-cha1nber 9. The bottom or edge of this part 11 when so arched preferably rests on the casing 2, the vertical sides of the flange 12 forming closures, so that the chamber 3 is closed at the ends of the part 11. Positioned in place alongside the burner part 11 is a pipe or tube 13, which forms the generating-chamber or vaporizer. This vaporizer has small vapor-outlet 14, opening through the air-tube 7 in line with the mixing-tube 8. As the burner 11 is extended down one side of the casing 2 and the vaporizing-tube or vaporizer 13 is arranged sidewise and transversely to this side burner or generating-burner 11 I am able to accomplish two important results. First, I am able to construct my burner with great compactness; second, to bring all portions of the outer surface of the vaporizer 13 between the inlet and outlet of the vaporizer into direct contact with the flame of said slotted side of the casing. This is of extreme importance in the vaporization of kerosene,

and it is equally of importance that the inlet end of the vaporizing-tube should not be directly in the heatingflame, as it is advantageous not to project the oil flowing in the vaporizing-tube into too great a heat at the point of its introduction into the tube.

15 represents the oil-sup )ly pipe, which is connected with any suitab e source of supply, preferably under gravity-pressure. This oil-supply pipe 15 is connected with the vaporizing-tube by a smaller portion or section 16. The object of making this section 16 smaller in diameter than the supply-pipe 15 is to prevent the supply of oil in pipe 15 and the metal of the tube from drawing the heat from the tube 13.

Preferably the tube 13 is inclined with respect to the horizontal, so that the inlet end is lower than the outlet. By thus inclining the vaporizing-tube 13 the natural tendency of the oil as it is heated to rise is taken advantage of, and the vaporizing-oil rising toward the upper end of the vaporizing-tube 13 is converted into vapor before it reaches the outlet 14. By thus arranging the outlet 14 above the inlet into the vaporizingtube the absolute vaporization of the oil. is insured and all possibility of non-vaporized oil flowing to the outlet obviated. Bytlu1spreventing the non-volatilized oil from appr aching the outlet end I am also able to provide the greatest heat in the outlet end of the tube 13, thusinsuring the most complete volatilization. This is of great importance with kerosene, as the same condenses rapidly.

17 represents a valve-casing, preferably of sufficient length to carry the packingdiox away from the heat zone, so that the heat from the burner will not deteriorate the packing, causing the valve to leak. inside of this casing 17 is a valve-stem 1.), which fits snugly within t,1e.casing 17 and has at its inner end a cylindrical pin-valve 18; adapted to operate in the vapor-outlet 14: of the vaporizing-tube 13. The stem 19passesthrough a suitable packing within a packing--box 20 and is provided with. a packing-nut 21. The stem 19 is provided with an. enlarged screwthreaded end 22, engaging a thread in the flange 23, thus providing the threaded prrts of large diameter outside of the packing-box; and pa king-nut. The stem 19 is provided with a suitable opera ting-head of the ordi nary or any preferred style or construction.

Inside the casing 2 and near thexportion of the wall thereof which the air-tube S terminates I provide a low wall 25, forming al separate cup 26. This wall is preferably extended up so that it'is slightly above the level of the bottoni 'of the chamber of the tube 8. The cup 26 thus formed is entirely out off by the wall 25 from communication with the other portion of the chamber 3, except over the wall 25. It is thus seen that in case the generator should -cool from any causesuch, for instance, as a sudden gust of wind blowing out the flame from the burner or from water boiling over when the burner is in operation-the oil forced through the tube 13 into the tube 8 will fill the cup 26; but as the wall 25 is slightly higher than the bottom of the tube 8 the oil will then run back out of the tube 8 and down the airchamber 9 into any suitable receptaeleior onto a stove-pan, as means are provided therefor, thus preventing the flooding of the entire chamber 3 and causing the prodinztion. of alarge amount of partially-burned and evilsmelling vapor.

Preferably formed integral with the flange 5 of the burner-top 5 is a hood 27, which, as shown, is extended out over the gene-ratin; cor vaporizing tube 13 and downward opposite the part 11 of the burner. This hood 27 preferably provided in its top with. an 0 )ening 28 directly above the vertical slots of the part 11, so that the flame from the upper portion of the burner and the flame from the side portion 11 of the burner are in communication, and each insures the continuous burning of the vapor issuing through the other.

29 represents a light filling within the vaporiz ing-tube 13, being shown in the draw-- ings as a series of twisted fine Wires. If preferred, gauze might be used in place of the wires, The object of this filling 29 is to prevent pufling of the burner. due to irregularity of the vaporization within the tube 13. The use of a light filling within the tube 13 distributes the heatevenly throughout the vaporizing-chamber, causingequal vaporization and also constant vaporization. ja-r'lhei use of such filling also prevents the deposit of carbon, as such light filling is more readilyheated to the same degree as is the wall of the v tube 13.

By extending the part 11 of the burner and generating-tube 13- at an acute angle to the tube 8 I am able to bring the vaporizing or generating tube 13 in closer proximity to the burner and secure great compactness.

It is preferable in constructing this burner to provide the tube 8 of such diameter as to provide an excess of air in the mixing-chamher 3, so that the vapor from the vaporizing tube 13 is mixed in the chamber 3 not only with just sufficient air to burn on the burner 5.

' vapor.

It is thus seen that with this construction andarrangement all parts of the burner-are in intimate relation with the heat zone and that no part of the mixing-chamber away a from the heat zone, so as to present any unheated surface to the vapor which. would cause condensation thereof. j

Preferably the top 5 of the burner is slightly depressed below the flange.5.- ()ne of the advantages thus secured is that the flange 5 prevents air from the outside of the burner mixing with the vapor asit rises from the mixing-chamber 3. This is found to be of advantage when. the burner is first lighted, and when the burner is being extinguished all of the vapor rising therefrom being thronghly consumed and no fumes are precipitated in the roolnwhen the burner goes out.

By arranging the generating-tube at the side .of the casin 2 much more ready access can be had to the tube 13 forstarting the burner in operation. 'It will also be noted that'witli this'burrielf the side portion of the flame heats the generator not only at its central portipn, but also at its upper and discharge end 1 a 30 represents a clean-out plug atthe lower end of the tube 13, by means of which ac cess maybe had to the vaporizing-chainber through whichthef light filling 29 may be removed and replaced, as desired. It Wlll be noted that this'clean-out plug as well as the oil-supp ly pipes 15 16 are outside the heatingame.

The vaporizing-tube 13 provides a single straight unitary vaporizing-chamberwherein equal vaporization of all of the kerosene is insured, and by the provision of the clean-out plug 30 this single straight unitary vaporizing chambermay be most readily cleaned of all deposits of carbon and impurities carried by the oil. It has been found in the use of kerosene-vapor stoves that it is highly important to provide against'such deposits in the vaporiZing-chamber, and to .accompish this desired result in the most simple manner I- have provided a single straight vaporizing-tube having a single unitary and straight vaporizing-chamber, the vaporizing-tube being arranged alongside of and transversely to the downwardly-extending slotted portion of the burner, so that I am able to combine the advantages of such a single straight unitary vaporizing-chamber and a unitary flame at the main burner and the vaporizing-burner and completely surround the walls of the vaporizing-chamber with the i lame. By arranging sueh vaporizing-tube transversely to or across the downwardly-extending side burner and at the side thereof the flame comes in intimate contact with all'portions of the tube and particularly with the lower portion of the periphery thereof. A marked advantage is secured by so arranging the vaporizing-tube, as. if the same is arranged sulostantially vertical the flame is not retained against the walls of the tube and the vaporizing-chamber is not ell'cctually heated. Fur thermore, by the construction shown the vaporizatio'n of the oil does not depend upon the conduction of heat from one portion of the vaporizer in direct contact with the [lame to other portions which are not in direct contact therewith, and 1 am also enabled to pro vide the greatest heat at the outlet end of the vaporizing-chainber.
